(148) wondering how they would act when released, which may be today. I happened to glance down the road toward the thrasher nest and saw Brown-eyes headed for me about 100 feet away. I did not call her, but she was running toward me like a road-runner and, of course, it meant that the nestling needed attention again. I therefore produced the box of worms and held some in my hand at about the level of the arm of the chair. Brown-eyes jumped up on to the toe of my shoe which was about a foot above the ground, as my legs were crossed, then up to my hand, taking four worms, which she prepared, then off at full speed down the road again. In about a minute she was back again, this time taking two worms. In about two minutes, Green-eyes, whom his mate had evidently told about the soft snap, also came running along the road toward me, stopped in front of me, looking at me expectantly but not offering to jump up. I dropped one worm at a time near my feet. He "prepared" each in the same way as his mate, and, between worms, watched me to see whether I would give him more. In this way he got three and headed for the nest on the road at full speed. The next trip was made by Brown-eyes, who took one. The next by Green-eyes, who took three. Brown-eyes was back once more and took one worm, which she ate herself. This meant, as Green-eyes did not reappear at once, that the saturation point at the nest had been reached. By actual timing this episode occupied a little less than 10 minutes. During this time the worms taken to the nest totalled 14 and the distance traversed by both birds aggregated 2,200 feet horizontally and 220 vertically. This tremendous, intensive stuffing campaign undoubtedly meant that the birds wanted some time off for themselves, so going back to Brown-eye taking the worm for herself, the next event consisted of a good meal for Brown-eyes from my hand, after which she ran up
